WB AGC (Bypass, Engage)

The wideband Automatic Gain Control (AGC) stage can be bypassed if desired, although more consistency is achieved when this stage is used.

AGC Drv (AGC Drive)

This control adjusts the amount of drive to the wideband AGC stage. Increasing the drive causes deeper compression to be achieved, and deeper compression allows quieter passages in the input audio to be raised further than if lesser drive (and less compression) was used.

AGC Att (AGC Attack)

The attack control adjusts how fast the AGC responds to sudden increases in audio level, and higher numbers equate to faster response times. Faster attack times reduce the transient nature of the input audio, while slower attack times improve it. Extremely slow attack times must be used with caution because allowances must be made in later stages to not overload them during the time when the broadband AGC is adjusting the level downwards.

AGC Rls (AGC Release)

The release control adjusts how fast the AGC recovers from periods of more gain reduction when the input audio levels fall. Faster release times (higher numbers) result in a more dense sound. Even though the Omnia uses program controlled release algorithms, setting the control for extremely fast release times can result in ‘pumping’.

Gt Thresh (Gate Threshold)

When the input audio falls below a certain level, the gain control action of the AGC stage is “frozen” by the gate. The level at which this freeze, or hold takes place is controlled by the setting of the Gate Threshold control. Higher numbers cause the gate to activate at higher audio levels. In most applications this control should be adjusted to cause gating action to occur when the input audio falls about 20dB below nominal. The action of gate also prevents noise rush up during periods of no audio or during pauses in speech.

RTZ Speed (Return To Zero Speed)

RTZ stands for Return To Zero. What RTZ does is return the gain of the WB AGC section to an internally determined amount of gain reduction in the absence of audio. RTZ speed controls how fast this adjustment takes place – i.e., how long it takes the AGC to move to the target RTZ platform level.

Enhancers

Deep Bass

Adds ‘girth’ to the audio by enhancing very low frequencies such as kick drum fundamentals or very low bass notes that may be present in the input audio program.

Phat Bass

An Omnia exclusive, Phat Bass adds harmonic overtones to the lower bass frequencies. The addition of these overtones causes small speakers to seem to produce bass response that they are
